The testing machine needs to meet the mechanical performance testing and inspection of rubber bearings, pot bearings, ball bearings, etc. for highways, railways, bridges, buildings, etc.
Vertical compression stiffness, vertical compression displacement, horizontal shear displacement, vertical compressive stiffness, compressive elastic modulus, shear elastic modulus,
horizontal shear (static shear), ultimate compressive strength, friction coefficient, rotation angle and other tests can be carried out to detect axial compression deformation and radial
deformation under load tests of bowl/ball bearings for highway bridges.
The static compression shear testing machine adopts a bottom mounted oil cylinder and a four column structure main unit, with a continuously adjustable testing space. It adopts a
multi-channel electro-hydraulic servo control system, and is controlled by a microcomputer to coordinate hydraulic loading, automatic continuous and stable loading, automatic load
holding, automatic data collection and storage, curve drawing, automatic printing of test reports, and real-time computer control of the test process, display of test force and test curve.
It is simple, reliable, and easy to operate. Fully digital electro-hydraulic servo closed-loop control, data processing, and data analysis integrated. This testing machine can draw time
test force, time displacement, displacement test force curves and automatically process test data according to testing requirements. It is an ideal testing equipment for transportation,
building materials, metallurgy, aviation, aerospace, universities, scientific research institutions, etc.
